SIEMENS 6ED1055-1FB00-0BA1 DM8 230R Expansion Module

Product Description

The SIEMENS 6ED1055-1FB00-0BA1 is a digital I/O expansion module from the LOGO! series, designed to extend the input/output capabilities of LOGO! logic controllers. This module provides 4 digital inputs (DI) and 4 relay outputs (DO), supporting 230V AC/DC power supply, making it suitable for industrial automation and building control systems .

Key Features & Advantages

Flexible Power & I/O Configuration
- Power Supply: Supports 115V/230V AC/DC, with a wide input range (100–253V DC / 115–230V AC) .
- Digital Inputs (4x): Compatible with AC/DC signals, allowing connection to sensors and switches.
- Relay Outputs (4x): Each relay can handle 5A resistive loads and 3A inductive loads, suitable for motor starters, solenoids, and lighting controls .
Compact & Easy Installation
- DIN rail mounting (35mm), requiring 2 TE (36mm width) of space .
- Compact dimensions (90 x 36 x 55 mm), ideal for control cabinets with limited space .
Robust & Reliable Performance
